Japanese Patent Application No. 10-172119, Japanese Patent Application No. 10-177896, and the like. However, since these construction work vehicles are full-fledged with a self-propelled work vehicle equipped with an aggregate dispersion device and a binder dispersion device, the production cost is high and the structure is complicated. There is.

[0003]

SUMMARY OF THE INVENTION The present invention solves the above-mentioned drawbacks of the conventional construction work vehicle and has a low production cost.
It is another object of the present invention to provide a simple spraying device having a simple structure and a simple spraying method using the simple spraying device.

[0004]

Means for Solving the Problems The present inventors have analyzed the minimum required functions of a spraying device at a construction site, and found that (1) at least that the aggregate can be sprayed, (2) If possible, the aggregate and the binder can be sprayed at the same time. (3) The spread width of the aggregate and the binder can be adjusted. (4) The spread amount of the aggregate and the binder can be adjusted. It has been found that it is only necessary to satisfy the four functions of:

[0005] Therefore, the present inventors have conducted intensive studies focusing on these functions. As a result, the above-mentioned aggregate dispersing device or the aggregate dispersing device and the binder dispersing device are mounted on a movable base having movable wheels. We found that we could solve the problem.

That is, the present invention provides a simple spraying apparatus in which an aggregate spraying apparatus is mounted on a moving gantry having moving wheels, or
Along with the aggregate dispersing device, a simple dispersing device including a binder dispersing device at a position forward of the aggregate dispersing device of the movable gantry in the traveling direction and at which no moving wheel intervenes with the aggregate dispersing device, The present invention solves the above problem by providing a simple spraying method using these simple spraying devices.

[0007] The movable gantry that constitutes the simple type spraying device of the present invention is provided with means for connecting to another vehicle in the forward direction in the traveling direction. By this connecting means, it is possible to connect to another vehicle, preferably a self-propelled aggregate supply vehicle, and to move the movable gantry as the aggregate supply vehicle travels. The other vehicle to be connected may not be an aggregate supply vehicle, and may be, for example, a binder supply vehicle or another self-propelled vehicle, but is mounted on the simplified type spraying device of the present invention. From the viewpoint that the aggregate can be supplied to the aggregate spraying device at any time, an aggregate supply vehicle is most preferable.

[0008] The aggregate spraying device provided in the simple type spraying device of the present invention has, for example, an aggregate receiving port at an upper portion and an aggregate outlet at which a spraying amount and / or a spray width can be adjusted at a lower portion. The aggregate bin usually contains a certain amount of aggregate, and the amount of the aggregate and / or the width of the aggregate can be adjusted. Sprinkled on top. Needless to say, new aggregate is supplied to the aggregate receiving port above the aggregate bin from an aggregate supply source such as an aggregate supply vehicle as needed.

[0009] A binder spraying device provided in the simplified spraying device of the present invention includes, for example, a spray bar and a plurality of spray nozzles attached to the spray bar.
By opening and closing the on-off valves provided on the individual spray nozzles, it is possible to adjust the spread width of the binder. Adjustment of the spraying amount is performed by adjusting a flow control valve provided upstream of the spray bar, or by changing a delivery pressure of a binder delivery pump.

In the above-described binder dispersing apparatus, the moving wheel of the moving pedestal is interposed between the moving gantry and the aggregate dispersing apparatus in the forward direction of the moving gantry. It is provided in the position where it does not. By adopting such an arrangement, the binder is first sprayed on the road surface, and then the aggregate is sprayed on the spreading surface, and after the binder is sprayed, Before the aggregate is spread on the distribution surface, the moving wheel of the movable gantry does not pass over the distribution surface of the binder. Therefore, there is no fear that the scattering surface of the binding material is disturbed and uneven by the moving wheels of the movable gantry, or the binding material adheres to the moving wheels and soils other road surfaces.

In some cases, the simplified spraying device of the present invention includes an auxiliary material spraying device near the binder spraying device on the movable gantry. The auxiliary material accelerates the decomposition of the binder and promotes the solidification, but is not limited to these.

[0012] The simple spraying device of the present invention is connected to another vehicle, preferably an aggregate supply vehicle, by a connection means provided in front of the traveling direction, and travels along with the aggregate supply vehicle. While receiving the supply of aggregate to the wood sprinkler at any time,
The present invention can be used for a simple spraying method in which a binder and an aggregate are sprayed. Also, in addition to the aggregate supply vehicle, while the binder supply vehicle accompanies, and while supplying the binder from the binder supply vehicle to the binder dispersion device as needed, the dispersion of the binder and the dispersion of the aggregate are performed. Can also be used for a simple spraying method. As described above, the simple type spraying device of the present invention has a simple structure, and can be sufficiently combined with other existing work vehicles or the like and used at the same time to sufficiently spread the binder and the aggregate. Can be done.

Hereinafter, the present invention will be described in detail with reference to the drawings, but it is needless to say that the present invention is not limited to those described in the drawings.

[0014]

DESCRIPTION OF THE PREFERRED EMBODIMENTS FIG. 1 is a side view showing an example of a simple type spraying device according to the present invention. In FIG. 1, reference numeral 1 denotes a simple spraying device, 2 denotes a movable gantry, and a movable wheel 2 is provided on the movable gantry 2. Reference numeral 4 denotes an aggregate bin as an aggregate dispersing device. The aggregate bin 4 is provided with a scatter width adjusting lever 5 and a scatter amount adjusting lever 6. Reference numeral 7 denotes a spray bar, a plurality of spray nozzles 8 attached in the width direction of the simple spraying device 1 along the longitudinal direction of the spray bar 7, and a supply pipe 9 for supplying a binder to the spray bar 7, and , Together with the binder receiving port 10 of the supply pipe 9 and the like, constitute a binder scattering device. Reference numeral 11 denotes a connecting means with another vehicle, 12 denotes a roll of the connecting means 11, 13 denotes an auxiliary leg, 14 denotes a work step, and 15 denotes a road surface.

In the standby state, the simple type spraying device 1 is not connected to another vehicle, and is maintained in a stable state by the standing auxiliary legs 13 as shown in FIG. On the other hand, in use, the simple spraying device 1 is
The auxiliary leg 13 is pivoted to a position shown by a dotted line in the figure so that the auxiliary leg 13 does not hinder the advance of the simple spraying device 1 while being connected to another vehicle, for example, a rear wheel 16 of the aggregate supply vehicle. Then, it is locked by locking means (not shown).
In this state, the aggregate bin 4 is supplied with the aggregate from, for example, the bed 17 of the aggregate supply vehicle, and the binder receiving port 10 is provided with, for example, a binder supply pipe from a binder supply vehicle (not shown). Be linked. Normally, the binder is ejected from the spray nozzle 8 by the pressure from the delivery pump provided in the binder supply vehicle. However, the simple spraying device 1 may be provided with a binder tank or a delivery pump. Of course.

In the example shown in FIG. 1, the simplified spraying device 1 includes both an aggregate spraying device including an aggregate bin 4 and a binder spraying device including a spray bar 7 and a supply pipe 9. Although it is mounted, in the example of FIG. 1, the spray bar 7 and the supply pipe 9 constituting the binder dispersing device are detachably attached to the movable gantry 2 so that they can be removed as appropriate. It is possible that only the aggregate dispersing device is mounted on the simple dispersing device 1. It is of course possible to mount only the aggregate spraying device without mounting the binder spraying device from the beginning. Further, as shown in FIG. 1, the aggregate bin 4 is moved so that the rear edge is higher than the front edge by H so that the aggregate from the aggregate supply vehicle described later can be received without any omission. It is attached to the gantry 2. The height of H is usually in the range of 10 to 50 cm, preferably 15 to 50 cm.
The range is preferably 25 cm, more preferably about 20 cm.

As is apparent from FIG. 1, the binder dispersing device is located forward of the moving gantry 2 in the traveling direction of the aggregate dispersing device, and there is no moving wheel 3 between the dispersing device and the aggregate dispersing device. Mounted in position. Since the binder dispersing device and the aggregate dispersing device are attached in such a positional relationship, when the simple dispersing device 1 is advanced to disperse the binder and the aggregate, the dispersing is performed. The moving wheel 3 passes over the scattered surface of the bonded material, and the aggregate is immediately scattered on the scattered surface of the bonded material without disturbing the scattered surface or making the scattered state uneven. it can. In this case, as the binder spraying device, the position of the spray nozzle 8 for actually spraying the binder is located forward of the moving gantry 2 in the traveling direction of the aggregate spreading device and between the spray nozzle 8 and the aggregate spraying device. Moving wheel 3
The supply pipe 9 for supplying the binder to the spray bar 7 and the binder receiving port 10
May be behind the aggregate dispersing device in the traveling direction of the movable gantry 2.

In another example of the simplified spraying device of the present invention, which is not shown, an auxiliary material spraying device is provided near the binder spraying device. The vicinity means that the auxiliary material spraying device is closer to the binder spraying device than the aggregate spraying device, and the bonding material and the auxiliary material sprayed from each of the spraying devices are on the spread road surface. Preferably, they are close enough to allow them to contact and mix with each other in the air while being sprayed. As the auxiliary material spraying device, similarly to the binder spraying device, a device configured by a spray bar, a plurality of spray nozzles attached to the spray bar, a supply pipe of the auxiliary material to the spray bar, and the like are used. Auxiliary material is usually supplied and delivered using an auxiliary material supply vehicle equipped with a tank and a delivery pump,
It goes without saying that the auxiliary material tank and the delivery pump may be mounted on the simple spraying device. The spraying amount and / or spraying width of the auxiliary material can be adjusted by controlling the opening / closing or opening of the individual spray nozzles or valves provided in the conduits, as in the case of the bonding material described later, or the delivery of the auxiliary material. Although it can be adjusted by raising and lowering the rotation speed of the pump, usually, the auxiliary material is always used in pairs with the binder, so that the amount of the auxiliary material sprayed from the spray nozzle for the auxiliary material,
It is preferable that the spray width is changed in conjunction with the spray amount and the spread width of the binder.

FIG. 2 shows the simple spraying apparatus 1 shown in FIG.
FIG. 2 is a plan view, and the same members as those in FIG. 1 are denoted by the same reference numerals. The connecting means 11 includes a rotatable roll 12
Is brought into contact with the inside of the rim of a wheel 18 constituting the rear wheel 16 of the aggregate supply vehicle, which is another vehicle, to connect the simple type spraying apparatus 1 to another vehicle, for example, an aggregate supply vehicle. . As another vehicle advances, the wheel 18 moves while rotating, and accordingly, the roll 12 also moves to the wheel 18.
The sprayer 1 rotates while maintaining the contact state with the vehicle, so that the simple type spraying device 1 proceeds in a manner to be pulled by another vehicle. Note that, as the connecting means 11 shown here, other connecting means may be used as long as the simple type sprayer 1 can be towed by another vehicle.

FIG. 3 is an enlarged view showing an abutting state between the roll 12 and the wheel 18. As shown in FIG.
The roll 12 is formed by a long groove 19 and a locking bolt 20.
It is attached to the connecting means 11 so as to be position-adjustable, and is configured so that it can be connected to vehicles having different sizes of wheels 18. Although there is no particular limitation on the material of the roll 12, hard rubber, plastic,
Metals and those obtained by lining a hard rubber on a metal surface can be used. In addition, in the connecting means 11 shown in FIGS. 1 to 3, three rolls 12 are provided on each side at an interval of 120 degrees with respect to each other. It is not limited to the illustrated one. As long as the rolls can be stably connected, the number of the rolls 12 may be one on one side, and even when a plurality of rolls 12 are provided, the intervals may be unequal. Further, the connecting means 11
The thing itself is not limited to what was shown in FIGS. 1-3, and it connects other vehicles and the simple spraying apparatus 1, and advances the simple spraying apparatus 1 with progress of another vehicle. Any connection means may be used as long as the connection can be made. For example, the simple spraying device 1 may be simply connected to the aggregate supply vehicle or another vehicle other than the aggregate supply vehicle with a rope, a wire, or the like, or the simple sprayer may be connected with a connecting rod formed of a rigid body. The device 1 and another vehicle may be connected.
Also, instead of the auxiliary legs 13 shown in FIG. 1, a movable wheel is provided at that position, and the movable gantry 2 itself is supported by, for example, four wheels.
The wheel moving gantry 2 may be towed by another vehicle such as an aggregate supply vehicle.

FIG. 4 shows an aggregate bin 4 as an aggregate spraying device.
And the same components as those in FIG. 1 are denoted by the same reference numerals. In FIG. 4, the aggregate bin 4 is provided with an inlet 21 for receiving the aggregate at the upper part, and an aggregate outlet 22 at the lower part of which the amount and / or width of the spray can be adjusted. The material discharge port 22 has a spray width adjusting roll 23 which is rotated by the spray width adjusting lever 5 and a spray amount adjusting door 24 which is slid up and down by the spray amount adjusting lever 6.
Is attached. Reference numeral 25 denotes a cover provided on the spray width adjusting roll 23, and FIG.
As shown in the drawing, only the shape of the arc that covers the spreading width adjusting roll 23 along the axial direction is gradually changed. Since the spray width adjusting roll 23 having such a cover 25 is attached to the aggregate discharge port 22 below the aggregate bin 4, the spray width can be adjusted by rotating the spray width adjusting lever 5 in the arrow direction. When the rotational position of the adjusting roll 23 is changed, the length of the aggregate discharge port 22 covered by the cover 25 in the width direction of the simple spraying device also changes, and as a result, the spread width of the aggregate can be adjusted. You can do it.

Further, when the spray amount adjusting door 24 is moved up and down by the spray amount adjusting lever 6, the vertical opening length of the aggregate discharge port 22 changes. As a result, it is possible to adjust the spray amount of the aggregate. You can do it. The mechanism for adjusting the aggregate width and / or amount is preferably the one shown in the drawing because it is structurally simple. However, if the aggregate width and / or amount can be adjusted, another mechanism can be used. Needless to say, it may be adopted. In the above description, the adjustment of the scatter width and / or the scatter amount of the aggregate is performed by adjusting the scatter width adjustment lever 5.
And by operating the spray amount adjusting lever 6, but in another example not shown, the spray width adjusting roll 2
A driving device is attached to each of the 3 and / or the spray amount adjusting door 24, so that the driving device can be remotely controlled by an operation panel or each driving device can be controlled via an I / O controller of a computer. ing. By controlling the rotation position of the spray width adjusting roll 23 and the vertical position of the spray amount adjusting door 24 by the computer in this way, the spray width and the spray amount of the aggregate are automatically changed according to a predetermined pattern. Adjust the amount of aggregate sprayed according to the traveling speed of the simple spraying device so that the amount of aggregate sprayed on the road surface is always constant even when the speed of the simple spraying device changes. Can be done easily. Further, as will be described later, it is also possible to easily change the scatter width of the aggregate in conjunction with the scatter width of the binder. In this manner, by interlocking the scatter width of the binder and the scatter width of the aggregate with each other, the aggregate can be scattered on a road surface on which the binder is not scattered, or even though the binder is scattered. There is no risk of inconvenience such that the aggregate is not sprayed. This means that if the width of the construction must be changed continuously during construction,
Especially effective.

It is also possible to provide a screw conveyor (not shown) in the aggregate bin 4. By rotating the screw conveyor, the aggregate in the aggregate bin 4 is transported in the width direction of the simple spraying device 1. The distribution of the aggregate in the aggregate bin 4 is made uniform. After the distribution of the aggregate is uniformed in the width direction of the simple spraying device 1 in the aggregate bin 4 in this way, the aggregate is sprayed with a predetermined width and a predetermined amount from the aggregate discharge port 22 toward the road surface 15. You. It is also possible to provide a vibration imparting device (not shown) in the aggregate bin 4 so as to make the distribution of the aggregate in the aggregate bin 4 uniform and to discharge the aggregate from the aggregate outlet 22. Is performed smoothly.

The aggregate outlet 22 is located at a distance of at most 50 from the road surface.
cm or less, preferably 30 cm or less, more preferably 2 cm or less.
Since the opening is provided at a position of 0 cm or less, even if the aggregate is dropped toward the road surface by gravity, the aggregate does not splash, scatter or roll on the road surface, and does not scatter outside the construction width. It is also possible to provide the entire aggregate bin 4 so as to be movable up and down with respect to the movable gantry 2. The aggregate bin 4 is provided with a heating and heat retaining means (not shown), and can heat or keep the aggregate therein as required.

FIG. 6 is a plan view showing the positional relationship between the spray bar 7 and the binder supply pipe 9 constituting the binder spraying apparatus. FIG. 7 shows a plurality of spray nozzles attached to the spray bar 7. It is a figure which shows the distribution state of the binder from FIG. As shown in FIGS. 6 and 7, a binder supply pipe from a binder supply vehicle (not shown) is connected to a binder receiving port 10, and the binder is supplied with a pressure from a delivery pump mounted on the binder supply vehicle. Through the receiving opening / closing cock 26,
After flowing into the supply pipe 9, it is sprayed as the binder 28 on the road surface 15 through the spray bar 7 and the spray nozzle 8. The number and intervals of the spray nozzles 8 attached to the spray bar 7 are not particularly limited.
It is mounted at m intervals, preferably at 7-15 cm intervals.

As shown in FIG. 7, the supply pipe 9 and the spray bar 7 are attached to the movable gantry 2 via an attachment device 29. The attachment device 29 is connected to the supply pipe 9 by bolts and nuts. The spray bar 7 may be attached to the movable base 2 in a semi-fixed manner, or may be one-touch detachable. For example, as shown in FIG. 8, as the one-touch detachable attachment device 29, as shown in FIG. 8, two semicircular fastening bands 30 are rotatably connected at one end, and the other end is temporarily engaged by a fastening pin 31. According to the attachment device 28 of FIG. 8, for example, the spray bar 7 is connected to two fastening bands 30.
The spray bar 7 is attached to the movable gantry 2 by inserting the pin 31 therebetween. At the time of removal, the retaining pin 31 may be removed, and the retaining band 30 can be rotated about the rotatable connecting portion so that the spray bar 7 can be removed.

The amount of the binder to be sprayed can be adjusted by adjusting the opening / closing state of an opening / closing cock 27 provided in each spray nozzle 8 or a valve provided in a binder supply pipe line from a binder supply vehicle (not shown). It can be adjusted by adjusting the degree of opening or by increasing or decreasing the rotation speed of a delivery pump provided in the binder supplying vehicle. The spray width can be adjusted by opening and closing the individual opening and closing cocks 27 of the spray nozzles 8. In FIG. 7, among the eight spray nozzles 8 in total, the left five spray nozzles 8 have the opening / closing cock 27 opened and the binder 28 is sprayed, while the right three spray nozzles 8 are sprayed. Nozzle 8 is open / close cock 2
7 is closed, and the bonding material 28 is not sprayed.

In another example not shown, the open / close cock 27 provided in each spray nozzle 8 and the receiving open / close cock 2 provided in the binder receiving port 10 are provided.
Each of the driving devices 6 is provided with a driving device so that the driving device can be remotely controlled by an operation panel or each driving device can be controlled via an I / O controller of a computer. By controlling the open / close state of the open / close cock 27 provided in each spray nozzle 8 and the receiving open / close cock 26 provided in the binder receiving port 10 by the computer in this way, the scatter width and the scatter of the binder are controlled. Even if the amount is automatically changed according to a predetermined pattern, or even if the traveling speed of the simple spraying device changes, the simple spraying is performed so that the amount of the binder sprayed on the road surface is always constant. It is easy to adjust the amount of the binder to be applied according to the traveling speed of the apparatus. It is also possible to easily change the scatter width of the binder in conjunction with the scatter width of the aggregate. The amount of the binder to be sprayed is determined by the rotation speed of a delivery pump provided in the binder supply vehicle, or by opening / closing an on-off valve provided in a conduit from the binder supply vehicle to the binder receiving port 10. In the case of adjusting by adjusting the condition, similarly, the control of the rotation speed of the delivery pump and the adjustment of the opening degree of the on-off valve in the middle of the pipeline are performed by the computer, and the receiving cock 26 and the individual It is preferable that the control is performed together with the opening / closing cock 27 provided in the spray nozzle.

In the above example, the simple spraying device 1 is not provided with a binder tank, and the binder transported into the simple spraying device 1 from the binder supplying vehicle through the receiving port 10 is not used. Is supplied to the spray bar 7 for the binder and the spray nozzle 8 as it is through the supply pipe 9, but a tank for the binder is provided in the simple type spraying apparatus 1 and the binder is temporarily stored therein. The stored and temporarily stored binder may be sent to the spray nozzle 8 by a binder delivery pump also mounted on the simple spraying device 1. As described above, when the simple spraying device 1 is provided with the binder tank and the delivery pump, the simple spraying device 1 can be used independently of the binder supply vehicle, and the degree of freedom increases. There are advantages.

In the simple spraying apparatus 1, a suitable heating and heat retaining means (not shown) such as oil, including a spray bar 7 and a spray nozzle 8, is provided in a tank and / or a pipe portion where the binder stays or passes. A heater or hot air supply means is provided to keep the binder at a constant temperature so as to maintain a predetermined property until the binder is sprayed from the spray nozzle 8. In addition, since the heating and heat retaining means including the spray nozzle 8 is provided as described above, for example, the remaining binder solidifies in the spray nozzle 8 and other pipelines and clogs the nozzle and the piping. Nothing.

FIG. 9 is a view showing an example of a simple spraying method using the simple spraying apparatus 1 of the present invention, and the same members as those described so far are denoted by the same reference numerals. In FIG. 9, reference numeral 32 denotes a dump truck as an aggregate supply vehicle. The aggregate 17 is loaded on the loading platform 17, and the loading platform 17 is slowly dumped up.
The aggregate is supplied to the aggregate bin 4 from. Numeral 33 denotes an aggregate chute, which is attached to the carrier 17 by suspension means 36 as shown in FIG. 10, and the aggregate falling from the carrier 17 may be scattered or spilled out of the aggregate bin 4. In this case, the loading platform 17 and the aggregate bin 4 are connected so as not to exist. As a matter of course, the opening of the aggregate chute 33 on the bed 17 side should be larger than the opening of the bed 17 and should be large enough to cover the opening of the bed 17. The opening on the bin 4 side must be smaller than the aggregate receiving port 21 of the aggregate bin 4 and sized to fit completely in the aggregate receiving port 21. Bed 17
If the distance between the carrier and the aggregate bin 4 is short, and the opening of the carrier 17 is small enough to fit in the aggregate receiving port of the aggregate bin 4, the aggregate chute 33 need not be used. It is. Returning to FIG. 9 again, 34 is a binder supply vehicle, 3
Reference numeral 5 denotes a supply pipe for a binder, the tip of which is connected to a binder receiving port 10 of the simple spraying apparatus 1.

In this state, when the aggregate supply vehicle 32 and the binder supply vehicle 34 are advanced toward the left side in FIG. 9, the simple spraying device 1 connected to the aggregate supply vehicle 32 also starts to advance. I do. When the simple spraying device 1 reaches a predetermined construction section, first, the binder spraying device is operated, and the binder 28 is sprayed from the spray nozzle 8 toward the road surface 15. Subsequently, when the aggregate dispersing device reaches the dispersing surface of the binder, the aggregate dispersing device is operated to disperse the aggregate 37 on the dispersing surface of the binder 28. If there is a change in the construction width on the way, the scatter width of the binder and the scatter width of the aggregate are changed in conjunction with each other, and accurate scatter is performed along the construction width. As described above, the operator can adjust the scatter width of the binder and the scatter width of the aggregate by using an operation panel (not shown) by an operator, or by causing a computer to perform the adjustment in accordance with the shape of a preset construction section. Is also good. If the speed of the aggregate supply vehicle changes during construction, the operator or computer changes the amount of binder and aggregate sprayed according to the change in the speed of the aggregate supply vehicle. A certain amount of binder and aggregate is sprayed. At the end of the construction of the binder supply vehicle, first, the binder dispersing device stops operating, then the aggregate dispersing device stops operating with a predetermined time difference, and the bone spreads on the binder dispersing surface without excess or shortage. Lumber is sprayed.

It is a matter of course that a dispersing device for the auxiliary material may be mounted on the simple type dispersing device 1 and the auxiliary material may be distributed simultaneously with the binder if necessary. In the above example, the binder supply vehicle 34 is used, and while the binder supply vehicle 34 advances together with the aggregate supply vehicle 32, the binder is dispersed and the aggregate is dispersed. When the mold dispersing apparatus 1 includes a binder tank and a delivery pump, it is not necessary to drive the binder supply vehicle 34. Binder supply vehicle 34
In order for the and the aggregate supply vehicle 32 to advance at a constant interval, the aggregate supply vehicle 32 is pushed by the binder supply vehicle 34, and conversely, the aggregate supply vehicle 32 is pulled by the binder supply vehicle 34. You may do it.
